-In Kubernetes, _namespaces_ provides a mechanism for isolating groups of resources within a single cluster. Names of resources need to be unique within a namespace, but not across namespaces. Namespace-based scoping is applicable only for namespaced objects _(e.g. Deployments, Services, etc)_ and not for cluster-wide objects _(e.g. StorageClass, Nodes, PersistentVolumes, etc)_.

 同一名字空间内的资源名称要唯一，但跨名字空间时没有这个要求。
